Abstract

A method for operating a drive device for a motor vehicle, said method includes: permanently supplying an entire exhaust gas of a drive aggregate of the drive device to a turbine of an exhaust gas turbocharger of the drive device via a variable turbine geometry and providing compressed air by means of a compressor coupled with the turbine for the drive aggregate; operating in at least one operating mode of the drive device in each operating point of the drive aggregate an electric machine, which is mechanically operatively connected with the turbine and the compressor, as a generator for braking the turbine; and braking the turbine by means of the electric machine the stronger the further a throttle flap arranged fluidly between the compressor and the drive aggregate is opened, while maintaining the operating point of the drive aggregate constant.
